When you open Action, you load the front and matte clips for the first media. You can then load any additional media. Use the Media menu to modify the front and matte clips.

The clips you load for each media appear in the Media list. The back clip you selected to access Action appears in the first row of the Media list and is assigned the letter B in the # column. The second row in the Media list contains the first front and matte clips you selected when accessing Action. The length of each clip appears in parentheses beside the clip name. A new line is added to the Media list each time you add media. For stereoscopic projects, you can apply media to the left and right eye.

You can sort the Media list by list number, front clip name, or matte clip name. As you view clips, you can look at the original front, back, or matte clip individually, as well as the results of colour correcting and keying a matte.

To access the Media menu, click Media in the Action menu. To help identify media, Alt+click a surface in the schematic, result, or camera view to automatically select the media in the Media list. If the Media menu is not selected, press Alt and double-click the surface to switch to the Media menu, and automatically select the media in the Media list. Also, when you select multiple surfaces, you can press Alt to select all associated media in the Media list. In this case, the first item selected is framed in yellow in the Media list as the current selection.
